Hair transplants are permanent, using follicles from the ‘safe donor area’ at the back of the head, resistant to balding. This permanence is based on Dr. Norman Orentriech’s ‘Donor Dominance’ theory, ensuring transplanted hair retains its bald-resistant traits. However, transplants don’t prevent future hair thinning or loss in untreated areas. Additional sessions may be required for large balding areas, to enhance density, refine the hairline, or address new hair loss. Particularly in younger patients, ongoing pattern baldness may necessitate further hair transplants for sustained appearance.
